I second ChanteyLass's suggestion of "Rocket." I was going to first it but I found the suggestion already in play as I read. :)

Kat, if you've paid any attention to Cesar Millan, be sure that as you blend this family that YOU are the pack leader. It makes it much easier on the dogs to know who is in charge.

My dogs have more than one syllable in their names, and still manage to know that I'm talking to them. I like the idea of having Luna and Rocket - you have a theme there.

My dogs have spice/seasoning names. I don't tend to give them people names any more, it confuses people in my life. (Please don't name her "Maggie").
